The Nicholas Gilman I found in Liberty was born abt. 1805. He was the one that moved with Ezekiel True Fogg and Ann True Gilman when they moved to Montville. He is the one I thought may have been Ann's brother(no proof). I went to familysearch.org I found a number of Nicholas Gilmans within a 10 year span + - 1797. I am unfamiliar with his family, so I don't know which if any he may be.
I could email you a pedegree chart for Ann True Gilman and Ezekiel True Fogg, but I don't know how to do it in this program. If I had your email address, I know how to send the pedigree chart that way. firstname.lastname@example.org is my address
